    Opis:
    Background: Conditioning activities such as resistance training can cause excitation of central nervous system resulting in Post-activation Potentiation phenomenon. Plyometric exercise also has an important role to develop Post-activation Potentiation following a resistance stimulus. So the purpose the study was to investigate the immediate effects of weighted plyometric exercise on sprint, agility and jump performance. Materials and methods: Twenty male university football players (age=21.3±1.5 years, body mass=63.3±9.5 kg, height=169.8±6.4 m) participated in this Single group pre-test post-test study. Agility Time (AT), Sprint Time (ST) and Counter-Movement Jump (CMJ) height were measured prior to and 1st and 5th minutes following plyometric exercise. Results: A repeated measures ANOVA employed at baseline (T0), 1 minute (T1), and 5 minutes (T5) post intervention showed significant effect for all the three outcome measures (p<0.001). Post-hoc Bonferroni pairwise comparison showed a significant decrease in both AT and ST from baseline to assessments at both T1 (p<0.001) and T5 (p<0.001), whereas there was a significant increase in the CMJ height. However, no statistical difference was found between T1 and T5 (p=0.058) in ST, but AT was significantly lower at T5 than at T1 (p=0.008), and CMJ height showed significant increase from T1 to T5 (p=0.001). Conclusion: Our results suggest that weighted plyometric exercises have an acute response on sprint, agility and counter movement jump (CMJ Height) following Post-Activation Potentiation (PAP) effect developed after plyometric exercises.

    Opis:
    The study assesses the effects of a six-week plyometric training program (PT) on muscle stiffness in the dominant and non-dominant leg in male collegiate volleyball players. The study group comprised 16 volleyball players who had played collegiate volleyball for at least four years. For six consecutive weeks, twice a week, the players undertook a plyometric program of 60-min training sessions, each preceded with a specialist warm-up. The analysis of the anterior muscles of the right and the left lower leg revealed a significant increase in stiffness in the muscles of the right leg and the left leg. No significant differences were found between the anterior muscles of the left lower leg and the right lower leg in particular weeks of the training program. The analysis of the posterior lower leg muscles revealed no significant differences, either in the consecutive weekly training microcycles or between the left leg and the right leg. The measurement of muscle tone and biomechanical properties of muscles can be used as a fast and direct assessment of plyometric training-related muscle fatigue. A similar level of muscle stiffness in both lower legs (symmetry) is a reflection of the appropriate selection of plyometric training loads.

    Opis:
    The low achievement of long jump athletes and the limited virtual-based aquatic plyometric exercises to increase lower extremity muscle strength are the gaps in this study. This study aims to increase lower extremity muscle strength of long jump athletes through virtual-based plyometric aquatic training. This research adopted a mixed methods research. This study involved participants from long jump athletes at the University of Tanjung Pura in Indonesia (n = 20). Participants were divided into two groups, namely an experimental group (n = 10) and control group (n = 10). The quantitative instrument involved a leg dynamometer for measuring lower extremity muscle strength. While, the qualitative instrument used in-depth interview. Quantitative data analysis was carried out through IBM SPSS to calculate descriptive statistics and normality, while the paired sample t-test to test differences in lower extremity muscle strength values in the experimental and control groups. Qualitative analysis was carried out through recording, describing and coding stages, which categorized into three themes. Based on quantitative results, it showed that virtual-based plyometric aquatic training was proven significantly increase lower extremity muscle strength (ps0.05), but there was no significant effect in the control group (p & 0.05). Qualitative results found out that most of the participants gave a positive opinion regarding virtual-based plyometric aquatics. Thus, this study confirms that virtual-based plyometric aquatic training can be used to increase lower extremity muscle strength.

    Opis:
    Purpose: Lower extremity power is an important physical capacity of a soccer athlete. Power represents, and can be modified by, the training of strength and speed. Pre-season and in-season training differs in the relative emphasis on these two quantities. It is nevertheless desirable that the mechanical power remain the same or become higher during the in-season period. The purpose of this study was to identify changes in quantities related to “explosive strength” and to check whether, in collegiate female soccer players, pre- and inseason lower extremity power will remain unaltered. Methods: Twenty collegiate female soccer players, representing all field positions, participated. Lower extremity power was assessed by a series of drop jumps executed from four different heights (15, 30, 45, and 60 cm). Mechanical power was calculated using subject’s mass, jump height, and acceleration due to gravity. This value was further normalized by body mass of each athlete to obtain the relative (or normalized) mechanical power. Results: The normalized lower extremity mechanical power was highest when landing from the 30 cm height for both pre- and inseason periods. However, contrary to expectations, it turned out lower during the in-season than during the pre-season test, even though no significant differences were found between the corresponding jump heights. Conclusions: It is concluded that altered, perhaps inadequate, training strategies were employed during the in-season period. Besides, advantages of adding the relative mechanical power as a season readiness indicator are underlined compared with relying on the jump height alone.

    Opis:
    Introduction: The obesity epidemic has begun in the 80s and is still spreading which makes it a serious social and medical problem for the contemporary world. WHO stated that obesity is a chronic disease which requires complex treatment (special diet, change in a life style, physical activity). Both, individual workout performed on the aerobic equipment and resistance training, are crucial for obesity treatment. Propagating healthy lifestyle and proper eating habits among the whole nation is the basis for preventing and curing obesity and overweight. Aim of paper: The aim of the research was to evaluate the diet and the body composition in a group of adolescence, aged 16-18 beginning yearly professionally designed fitness program. Material and methods: The group of 90 girls and 64 boys began a specially designed fitness program which lasted 12 months. The nutritional state together with the body composition was evaluated with the use of bioelectrical impedance method (equipment InBody 220, producer Biospace). Results: The average BMI of the beforehand mentioned group was 23.3 [kg/m2] in girls and 24.4 [kg/m2] in boys. Although the BMI was close to normal the average amount of body fat was too high in girls (28.7%). In the group of girls the BMI showed a proper weight, however the amount of body fat was too high, it was suggested that the amount of fat tissue was decreased while the amount of skeletal muscles was increased. These data show that the proper body proportions were shaken. Conclusions: Professional equipment used for evaluation of the body composition helps to create a detailed program for fat reduction and muscle tissue growth together with creating a professional individual training program.
    Wstęp: Epidemia otyłości notowana od lat 80. XX wieku trwa nadal, stając się poważnym problemem medyczno- -społecznym współczesnego świata. WHO uznała otyłość za przewlekłą chorobę wymagającą kompleksowego leczenia z zastosowaniem właściwej diety, zmiany stylu życia z uwzględnieniem aktywności fizycznej. Promocja zdrowego stylu życia oraz właściwych nawyków żywieniowych adresowana do całej populacji stanowi podstawę prewencji i leczenia nadwagi i otyłości. Celem pracy była ocena stanu odżywienia i parametrów składu ciała w grupie młodzieży w wieku 16-18 lat rozpoczynającej 12-miesięczny programowany trening fitness. Materiał i metody: Grupę badaną stanowiło 90 dziewcząt i 64 chłopców, zakwalifikowanych do długofalowych badań oceniających wpływ ćwiczeń fizycznych na parametry składu ciała i wybrane wskaźniki biomedyczne. Stan odżywienia i skład ciała badanych oceniano metodą impedancji bioelektrycznej z zastosowaniem urządzenia InBody 220 (producent Biospace). Wyniki: Średnie wartości BMI w badanej grupie młodzieży wynosiły 23,3 u dziewcząt i 24,4 u chłopców i mieściły się w granicach przyjętej normy. Pomimo prawidłowych wartości wskaźnika BMI w obu badanych grupach procentowa zawartość tkanki tłuszczowej u dziewcząt przekraczała optymalne wartości i wynosiła 28,7%. Analiza komputerowa składu ciała pomimo prawidłowych wartości BMI wskazywała w grupie dziewcząt potrzebę redukcji tkanki tłuszczowej przy jednoczesnym wzroście masy mięśni szkieletowych. Wnioski: Badanie składu ciała z zastosowaniem urządzeń wyposażonych w komputerowe analizatory pozwala precyzyjnie określić skład ciała badanych i wskazać kierunki prawidłowego indywidualnego programu treningowego.
